It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) forbade employing a laborer before determining his wages, forbidden najsh sale, forbidden sale by touching, and forbidden sale by throwing a stone.

It is narrated from Sayyiduna Awf bin Malik Ashja'i, may Allah be pleased with him, who says: We participated in a battle in which our commander was Sayyiduna Amr bin Aas, may Allah be pleased with him. It happened that we were afflicted with severe hunger. We passed by a people who had slaughtered camels. I (Awf) said to them: If you let me eat from these, I can prepare the meat, etc., for you. They said: Fine. So I did their work and they gave me something to eat. I took it to Sayyiduna Umar bin Khattab, may Allah be pleased with him, but he refused to eat. Then I went to Sayyiduna Abu Ubaidah bin Jarrah, may Allah be pleased with him, but he also refused to eat. Then, when on the occasion of the conquest of Makkah I was sent to the Messenger of Allah, peace and blessings be upon him, he asked: Are you the ones with the camels? I said: Yes, O Messenger of Allah! The Messenger of Allah, peace and blessings be upon him, did not say anything more than this.

It is narrated from Sayyiduna Ali (may Allah be pleased with him), he says: Once, when I was in Madinah, I became extremely hungry, so I went out towards the upper part of Madinah in search of some work. Suddenly, I saw a woman who had gathered clay and now wanted to make mortar from it. I went to her and agreed to take one date for every bucket (of water). So I drew sixteen buckets of water from the well, due to which blisters appeared on my hands. Then I brought that water and poured it on the clay, and then I came to that woman to receive my wages and spread my palms before her. The narrator Ismail described the manner by spreading and joining his hands. So the woman counted out sixteen dates and gave them to me. Then I took those dates and went to the Noble Prophet (peace and blessings be upon him) and told him the whole story. So the Prophet (peace and blessings be upon him) ate those dates with me.

Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty said: On the Day of Resurrection, I will be the opponent of three persons, and whomever I oppose, I will overpower him: (1) The person who made a covenant in My name, but then broke it; (2) The person who sold a free man and consumed his price; and (3) The person who hired a laborer, took full work from him, but did not pay him his wages in full.

Another hadith is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), in which it is stated: The Noble Prophet (peace and blessings be upon him) said: On the last night of Ramadan, the people of my Ummah are forgiven. Someone asked: O Messenger of Allah! Is this the Night of Power (Laylat al-Qadr)? He (peace and blessings be upon him) replied: No, rather the fact is that when a worker completes his work, he is given his full wages.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) had cupping done on the two veins of the neck and between the two shoulders. A slave of Banu Bayadhah performed cupping for the Prophet (peace and blessings be upon him), and his wage was one and a half mudd. So the Prophet (peace and blessings be upon him) negotiated with his owners for a concession, and they reduced it by half a mudd. Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says that the Prophet (peace and blessings be upon him) gave the slave the wage for cupping; if it had been unlawful, the Prophet (peace and blessings be upon him) would not have given it to him.

It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) had cupping done, and when the cupper finished, the Prophet (peace and blessings be upon him) said to him: "How much is your wage?" He said: "Two sa’." Then the Prophet (peace and blessings be upon him) bargained with him for a reduction of one sa’ and ordered me to pay him, so I gave him one sa’.

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that Abu Taybah performed cupping for the Messenger of Allah, peace and blessings be upon him. The Prophet, peace and blessings be upon him, gave him a sa’ of grain and recommended his master to make things easy for him, so they reduced his burden.

It is also narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) had cupping done and he would not withhold anyone’s due (i.e., he would give him his wage).

Narrated by Sayyiduna Abdur Rahman bin Shibl (may Allah be pleased with him): The Messenger of Allah (peace and blessings be upon him) said: Recite the Qur'an and do not make it a means of livelihood, nor seek abundance of wealth through it. Do not distance yourselves from its recitation, nor fall into exaggeration regarding it.
